<h2><em><u>Solution with steps</u></em> : </h2><h2><u>Solution (A)</u> : </h2>
Money invested by a man = $10,500
No.of years for which he invested his money = 7
Rate of interest = 5.5%
We know that :
![\tt \: Simple \: interest = \frac{Principal × Rate × Time}{100}](https://tex.z-dn.net/?f=%20%5Ctt%20%5C%3A%20Simple%20%20%5C%3A%20interest%20%3D%20%20%5Cfrac%7BPrincipal%20%C3%97%20Rate%20%C3%97%20Time%7D%7B100%7D%20)
Principal = 10500
Rate = 5.5%
Time = 7 years
Simple interest the man payed :
![= \tt\frac{10500 \times 55 \times 7}{10 \times 100}](https://tex.z-dn.net/?f=%20%3D%20%20%5Ctt%5Cfrac%7B10500%20%5Ctimes%2055%20%5Ctimes%207%7D%7B10%20%5Ctimes%20100%7D%20)
![= \tt \frac{4042500}{1000}](https://tex.z-dn.net/?f=%20%3D%20%5Ctt%20%5Cfrac%7B4042500%7D%7B1000%7D%20)
![\color{plum}=\tt 4042.50](https://tex.z-dn.net/?f=%20%5Ccolor%7Bplum%7D%3D%5Ctt%204042.50)
Therefore, the simple interest payed by the man = <u>$4042.50</u>
<h2><u>Solution (B)</u> :</h2>
Money invested by the man (principal) = $10,500
The simple interest he payed = $4042.50
We know that :
![\tt \: amount = principal + interest](https://tex.z-dn.net/?f=%5Ctt%20%5C%3A%20amount%20%3D%20principal%20%2B%20interest)
The amount the man collected after a period of 7 years :
![= \tt10500 + 4042.50](https://tex.z-dn.net/?f=%20%3D%20%5Ctt10500%20%2B%204042.50)
![=\tt 14520.50](https://tex.z-dn.net/?f=%20%3D%5Ctt%2014520.50)
Thus, amount = $14520.50
Therefore the amount he collected after a period of 7 years = <u>$14520.50</u>

(-20,0) (0,-4)
Step-by-step explanation:
Distance formula is: d = v * t ( t = h ) and we also have 20 miles at the start.
Answer:
B ) d = 58 h + 20
